Not bad,but too simple. As the width is shallow,the cork bark gives it a quite unnatural look, especially with another cork bark infront. You kill the depth look.One dimension.. What i would have done is have a plastic mesh behind and encourage creepers to grow on it. Or, a moss wall.
Do not be offended.I say what i see and think. Also the pitcher plant is too big and distracting.
BUT for a starter, this piece of art surely will encourage and promote viva builders.
Good work!!
